Ask any athlete in the green room, decision maker in the boardroom or amateur forecaster on the sofa. There is one eternal certainty that rings true for every NFL Draft: nothing is certain. Everything known—from the combine to scouting reports to the rumor mill—pales in comparison to what’s not known.

ESPN The Magazine’s NFL Draft Preview Issue, which hits newsstands Friday, May 2,features Louisville quarterback Teddy Bridgewater on the cover. Since his subpar pro day, his critics have only grown louder. But so has his inner voice, reminding him of the strength it took to get here. This time last year, Bridgewater was the hands-down No. 1 quarterback of the 2014 NFL draft. He has everything a team wants: strong arm, good character and high football IQ. But now scouts and GMs wonder if his success is a product of a weak schedule and if Bridgewater is too quiet to lead an NFL team. Nonetheless, if a team drafts Bridgewater and starts him as a rookie, he’ll become one of very few QBs from single-parent households. In the cover story, “Never in Doubt,” The Mag’s Tim Keown takes a look at both the role Bridgewater’s upbringing played in his demeanor and the role socioeconomics play in becoming an NFL QB.
